The rewind starter mechanism is
mounted on the starter post in the
fan housing, directly in front of the
flywheel. Its main components are
the starter rope with grip, rope rotor
with rewind spring and pawl. A spring
clip holds these components in
position on the post. The starter
rope, which is wound onto the rope
rotor by the pre-
loaded rewind spring, rotates the
rotor when the starter grip is pulled.
This causes the pawl to be moved
outward by the spring clip and
engage the flywheelhub.
The torque produced by the starter
rope is thus transmitted positively via
the flywheel and turns the crankshaft.
The withdrawn starter rope is auto-
matically rewound onto the rope rotor
by the preloaded rewind spring.
The rewind starter mechanism is
practically maintenance-free. Only
the rope rotor post needs to be lubri-
cated with non-resinous oil at regular
intervals.
Remedy
Replace starter rope
Replace rewind spring
Thoroughly clean rewind starter
Apply a little paraffin to the rewind
spring, then pull starter rope
carefully several times until
normal action is restored
Cause
Rope pulled out too vigorously
as far as stop or not
pulled vertically
Spring overtensioned - no
reserve when starter rope is
fully extended
Rewind starter mechanism very
dirty (dusty conditions)
The lubricating oil on the rewind
spring becomes viscous at very
low outside temperatures
(spring windings stick together)
